Accessibility Statement

Last updated October 12, 2026.

Our aim

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. The site has not yet been independently audited, so we cannot claim full conformance.

What we have built in

• Pages work with a keyboard alone, with visible focus outlines and a skip link to the main content.
• Form fields have labels and the calculator results are written as plain text.
• Layouts adapt from small phones to wide screens, and text can be enlarged.
• The site follows your light or dark color setting and respects the "reduce motion" setting.
• Menus and tables can be used without a mouse. Wide tables scroll sideways inside their own box.

Known limits

• Some decorative animations and background images have not been tested with every assistive technology.
• Results update as you type, and we have not yet tested how every screen reader announces those changes.

Tell us about a problem

If you find something hard to use, please tell us what page you were on, what you were trying to do and what device or assistive technology you use. A contact email address is being set up. Until it is live, you can write to us by post at the registered office below. We will reply and try to fix it, or offer another way to get the information.
